How to give own bot permission to see categories? - python-3.x

Question

My bot has a Command that creates a Category, and inside it, a Text and Voice channel. On creating the Category I overwrite the permission to let only a certain role to see that category and its channels.
Everything until this works fine. My problem comes when I want my bot to see the text channel, so he can read and interact with messages. My bot doesn't have any extra role aside from the Discord App one.
So far, this are the solutions I tried:
Set Bot to Administrator: This solution works, but want to discart it, since I don't know if it is recommended to set your bot as Administrator, and I believed there should be other ways to solve the problem.
Add Permission to Category, setting my bot role to let him read and write messages, like this:
await category.set_permissions(bot_role, read_messages=True, send_messages=True, connect=True)
This throws an discord.errors.Forbidden: 403 Forbidden (error code: 50001): Missing Access error, which I don't understand since I have all permission set in my oauth page (see photo below).
I have also tried to give the same permissions to the text channel, but it throws the same error.
All I really want is my Bot to read messages in that text channel, since he won't respond to any command if the Bot can't see the channel.
Edit:
This is how I created the category and channels:
async def prepare_game(ctx):
guild = ctx.guild
role = await guild.create_role(name=role_name)
category = await guild.create_category('Game')
await category.set_permissions(role, read_messages=True, send_messages=True, connect=True, speak=True)
text_channel = await guild.create_text_channel('Board', category=category, sync_permissions=True)
voice_channel = await guild.create_voice_channel('Room', category=category, sync_permissions=True)
Then at the end, I added the await category.set_permissions(bot_role, read_messages=True, send_messages=True, connect=True)line, where bot_role is my app bot role

Try setting the permission overwrites for ctx.guild.me (the bot user itself).
From the docs, set_permissions will accept a Role or a Member.
For example:
async def prepare_game(ctx):
guild = ctx.guild
role = await guild.create_role(name=role_name)
category = await guild.create_category('Game')
await category.set_permissions(role, read_messages=True, send_messages=True, connect=True, speak=True)
await category.set_permissions(ctx.guild.me, read_messages=True, send_messages=True, speak=True)
text_channel = await guild.create_text_channel('Board', category=category, sync_permissions=True)
voice_channel = await guild.create_voice_channel('Room', category=category, sync_permissions=True)
