How can I insert a table in the text?

I added a picture. There is visible text, my cursor and an editor that does not have three dots for an additional menu where it could be possible to add a table.

?

this is the inline fast editing, you must edit the block by clicking the edit button (pencil in the orrange toolbar on mouseover)
then you will get all the options

I attached a picture - I don't understand where such an option appears, in which menu?

ok let's do it from the beginning
1. edit your text addon

2. edit the text with the full joomla standard editor

I am attaching a this video - which shows that I do not have access to the Text tab, which allows me to edit the text.

And a mega question, how do you show in your picture that you have the Joomla TinyMCE editor open and PageBuilder CK at the same time (you said you can't have both)?

you must not "click" on the text, check your video and my screenshot : when you hover the text you will get the orange toolbar >> this is the edition of the addon (text)
the green toolbar is the column
the grey toolbar is the row
